'Application med my 2s, 1917. senal No. 182,194..

T o all whom z't may concern'.'

Be 'it known that I, OoxA LUDEKE'NS. a f

citizen of the United States. residing at San rancisco, inthe county of San Francisco and State of California, have invented new andvnseful Improvements in Soap and Processes of Making the Sallie, of whichthe following is a specification. 5 y

The object of the present invention is to proy ide a soap which can be used without wa'ter, and which' is therefore very 'useful to personsemployed in a variety of occupations,s uch as actors, chauffeurs, printers, machinists, and mechanics generally, railroad and street-car men, boot blacks, cobblers, and creosote workers. To make the soap, to two quarts of water heated to a temperature of 200 F. li's'addedV one pound of neutral soap chips containing al moisture Acontent of 12%. The temperature ofthis mixture is then raised to lboiling point and maintained thereat untilthe soap 4chips are thoroughlyv dissolved. temperature of the mixture islthen redugeed to 160Q-afl?, To the mixture is thenadi d onel qua-'rt of boiling water containing:` solved therein. 6 ounces then increased to :260 F. and is maintained at this degree for 1.5 minutes, when'there is added 195 ounces of parawax. Still maintaining the mixture at the sametemperature fork 10i-minutes, there is then addetlorief ounce offrelined beeswax. during which the mixture is maintained: t'fthe same temperature, there are added 3 quarts of water at a temperaturevof/LLO". The mass is then allowed, tocool to 90", F.

It is then agitated and also aer'ated, but not excessively, for an excessive 4aeration would result in the mixture containing numerous large and weak air bubbles which would collapse immediately7 before or upon use.

In the accompanying drawing, Figure` 1 is a longitudinal section, and Fig. 2 is a cross-section, of a vessel which I have found suitable'for sutiiciently agitating and aerat-V ing the mixture. .i

Referringto the drawing, l indicatesfa.A

vessel having a round bottom 2 andafclosed top ".Itissurrounded by a water-jacket .longitudinally through said vessel is a sha pulley The After 10 mnlt s,

6 extending through bearings 7 4on the ends 8 of the vessel and rotated by a grooved From said shaft extend diametrically opposite to each other pairs of beaters l0 'each pair connected by a single, blade 11, and also diametrically opposite to each other and at right angles to t-he Patented Aug. 2o, 191s.

beaters l0, pairs of beaters 12, each pair having two blades 13 distances from the axis tively greater and less This mixture should be connecting them at of the mixer respecthan the blades l1. rotated for fifteen minutes at a speed of twenty-seven revolutions a minute. x

In use a small quantity of the soap is rubbed on the part to be cleansed until' the lather-and dirt are thoroughly mixed, and they are then removed by a piece of paper, waste, or saw dust. It the hands are very dirty. first remove the first mixture and then use a little more of the soap.

It is believed that the agitation of the mixture of water and soap dissolved therein with parawax and beeswax at a 'high temperature has the effectV parawax and beeswax to form minute enA `of carbonategflof soda. 'The temperature of the mixture is of causing the velops -or capsules inclosing the liquid soap, which capsules are broken and the liquid soap is released when the soap is used.

I claim:

1. The process of making soap 'which consists in adding to hot water having soap dissolved therein parawax or beeswax substantially in the proportion specified, and then, after allowing the mixture to cool to normal temperature, agitating and aerating the same. n

2. The process of making soap, which consists in mixing a hot, soapy liquid with parawax substantially in the proportion specified, and then agitating and aerating the same to reduce it to a paste like form.

3.' The process of making soap, which consists in mixing a hot, soapy liquid with a substance vcapable of forming minute comparatively durable -envelops inclosing 'the liquid, and then agitating the mixture to re- .-a-w'axy substance, and1 then agltating and aerating the mixture to reduce it to a paste like form.
